The Apple Music announcement has seen its share of positive and negative critical reactions, including some from Apple’s streaming service competitors.

One such reaction was quickly erased, though Mashable was able to take a screenshot of Spotify CEO Daniel Ek’s reaction during the Apple press conference yesterday.

Following the announcement, Ek simply tweeted “Oh ok,” but he soon deleted his tweet.

A more official response came from Rdio, which released an official statement welcoming Apple to the music streaming arena.

“We look forward to responsible competition in the massive effort to make music available legally for anyone to enjoy anytime, anywhere,” the statement reads.

SoundCloud CEO Alexander Ljung, speaking at the Midem Music Industry Conference yesterday, reportedly commented on Apple’s new project.

“They’re going to put a lot of marketing behind this. I’m all for it,” he said according to VentureBeat. “The amount of listening happening on streaming is still very small. Apple is going to rapidly increase the market for all of us,” he later said.

Rhapsody also had a polite way of reminding users that its plan will be cheaper than Apple Music, which will cost $9.99 a month after a three-month complimentary trial period.

Apple announced Apple Music, which is due out June 30, at its WWDC on Monday, and explained that it would be a music-purchasing app, a streaming service, a social network, and a radio station, all in one. Here’s everything you need to know about Apple Music.
